We, who think like animals living in small groups, must structure a global world. We believe in universal human rights and believe racism and war are wrong. On the other hand, it is our nature to be cooperative and loving almost exclusively with the members of the group to which we feel we belong.

Personally, I think it is possible to build a society that is moral on a nonreligious basis, but the jury is still out on that.

When it comes to social interaction, the chimpanzees appear to be just as intelligent as we are.

We are by far the most contradictory of all primates. An animal with this much internal conflict has never lived on this earth.

Unlike the primate hand, the elephant's grasping organ is also its nose. Elephants use their trunks not only to reach food but also to sniff and touch it. With their unparalleled sense of smell, the animals know exactly what they are going for. Vision is secondary.

A chimpanzee who is really gearing up for a fight doesn't waste time with gestures but just goes ahead and attacks.

When someone brutally kills someone else, we call him "animalistic." But we consider ourselves "human" when we give to the poor.
